hinge

I found this with a metal detector. I tried to find out the age but no luck. The numbers on the back mean the sand molds. I looked it up months ago but there was not much info on it. I know one hinge doesn't do much but it is really well made and someone put alot of time and craftsmanship into it. What I did find out it might have been made in the 1800's but I dont know that for sure. I was hoping someone that needed one are knew what year it is will let me know.
